GRAIN-REEL FOR REAPENG'f-lVl/lCl--IINE S.,`

SPECIFICATION forming part of LettersiPatent No. 606,346, dated June 28, 1298. Application not my 4. 1897. seria No. 634,999. (Nq man.)

To al?, whom it may con/007%:

Be itkn own that we, MARSHAL Gr. KEEN and PETER P. KEEN, of Keensburg, in the county of lVabash and State of Illinois,have invented a new and Improved Grain-Reel for Reaping- Machines, of which the following` is a full, clear, and exact description.

This invention relates to reels for reaping machines; and the object is to provide a reel that will take up a small space as compared with the ordinary reels that describe a complete circle in their movements, and, further, to provide a simple means whereby the reel may be adjusted relatively to the cutters, and, further, to so construct the reel that it may be folded down closely upon the platform making it much more convenient for transportation or storage.

lVe will describe a reel for reaping1na chines embodying our invention, and then point out the novel features in the appended claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. Figure 1 is a front elevation of a reel embodying our invention. Fig. 2 is an end elevation thereof, and Fig. 3 is a sectional detail showing the means for supportin g the reel.. Referring to the drawings, 1 designates the platform of the usual construction and upon the forward edge of which the cutter-blades are mounted. This platform is extended from the frame portion 2 of the reaper. Mounted to swing on the frame 2 is a linkY 3, and mounted to swing on this link 3 is a reel-supporting link 4. These two links 3 and 4 form, in effeet, toggle-links for supporting and adjust` ing the reel. These two links for the purpose of strength are made substantially in the form of rectangular frames, and they have trunnion connections one with the other.

Attached to the upper end of the link 4 and extending lengthwise of the platform 1 is a secured to the shaft G, and the sprocket-wheel 9 will of course bebetween the adjacent ends of the tubular shafts 5 and S. f.Supported by the tubular shafts 5 andS are guideways for the sprocket-chains 11 and 12,the inner guideway being connected to the tubular shafts 5 and S by hangers@ Z1. The outer guideway is connected to the tubular shaft S by a hanger a' and is also supported from the shaft G by a hanger 1)'. These guidcways each comprise diverging side portions 13 and 14 and a bot tom portion 15, formed in the arc of a circle.

ver 1S, having a link connection 19 with acollar 20 on the tubular shaft 5 above the link 4. The lever 18 has a dog movable relatively to `it and designed to engage with an arcshaped rack 21 to hold the parts adjusted, as is usual insuch cases. e Also pivotally con nected tothe frame 2 is another shifting le ver 22, having a link connection 23 with the lower link 3 of the toggles. This lever will also be provided withV means, as a thumblatch, engaging a rack 21 for holding it as adlj usted. It will be seen by operating the levers 1S and 22 that the reel may be swung forward or rearward relatively to the knives, as may be desired, and also that the reel may be elevated or lowered relatively to the reaperplatform, as occasion may require.

In operation the motion imparted to the shaft 6 will rotate the sprocket-wheels 9 and 10, and consequently the sprocket-chains will breakage inthe vicinity of brush or other 0bn structions7 and in ease of transportation of the machine on trucks it is obvious that the reel may be turned in over the platform out of the way. The two levers make it possible to adjust the reel in any desired position, so thatlodged grain may be recovered much more easily than in machines where the old i'orm of reel is employed. The shape of the guideways will enable the reel-boards to have a direct upward stroke on the rear side, which when the reel is properly adjusted in front of a knife will Serve to lift the lodged grain from the cutter-bar onto the platform, so that it may be conveyed to the binder.

Another advantage of this form of reel over the old style is that by shifting the inner sprocket chain on its sprocket Wheel the boards may be adjusted to run diagonally, with the inner ends somewhat forward of the outer ends, thus causing the grain to fall straight onto the platform.

Having thus described our invention, we

claim as new and desire to secure by Letters Patentl. In a reaping-machine,togglelinks mounted to swing on the frame thereof, means for swinging said links, relatively to the platform and one relatively to the other, a tubular shaft carried by the upper link, a reelshaft extended through said tubular shaft, means for rotating said reel-shaft, sprocketwheels on said shaft, sprocket-chains engaging said wheels, guideways for said sprocketchains, comprising downwardlydiverging side portions, and a bottom portion suspended in the arc of a circle, and reel-boards attached to the chains, substantially as speciied.

2. In a reaper, a link pivotally connected to the frame thereof, another link pivoted to the first-named link, levers having link connections with said links, means for holding the levers as adjusted, a tubular shaft sup,- ported by the upper link, a reel-shaft extended through the tubular shaft, means for rotating the reel-shaft, sprocket-wheels on the reelshaft, another tubular shaft on the reel-shaft between said sprocket-wheels,guideways supported by the tubular shafts and each comprising downwardly-diVerging side portions and bottom portions formed in the arc of a circle, rollers at the junction of the side and bottom portions, chains movable in the guideway and engaging with the sprocket-wheels, and reel-boards attached to said sprocketchains, substantiallyas specified.

3. In a reaping-machine, a reel, and means for causing said reel to travel in the arc of a circle at its lower portion and in an inwardlyinclined direction at the front and rear, substantially as speciied.
